That introduces a phrase that is essential to the meaning of the sentence.
Monica just read the book that I recommended to her.
Tamar has special skills that qualify her for a leadership role.
That refers to a particular book and to specific skills.
Which introduces a phrase that can be left out of the sentence without affecting the meaning; it is parenthetical.
The women’s organization, which meets on Tuesdays, invited Sheila to speak.
The fact that the organization meets on Tuesdays has nothing to do with Sheila’s being invited to speak.
Alternatives to which:
Use possessives: Our company, which relies on external resources, …. Our company’s reliance on external resources….
Use participles: Allied Building, which leads the field, ….
Allied Building, leading the field, ….
Just eliminate: Allied Building, which is based in Jerusalem,… ….
Allied Building, based in Jerusalem, ….
